To all whom it may concern:

Be it known that I, WELLS R. SToKELY, citizen of the United States, residing at St. Augustine, in thercounty of St. Johns and State of Florida, have invented new and useful lm rovements vin Car Ventilation, of which t e following is a s eciiication.

My invention has to o with car ventilation; and it has for one of its objects to provide a car designed more especially for the transportation of' fruit with means which, without materially inc-reasing the cost of the car or detractin from the carrying ca acity thereof, is calcu 'ated to maintain at al times and under all conditions a dry and otherwise wholesome atmosphere in the interior of. the car, this with a view of lessening the liability of the fruit being deteriorated while en route from one point to another.

Another object of the invention isthe rovision in combination with means for lea in atmosphericair into the interior of a car an exhausting vitiated air from such interior, of means whereby the temperature of the `air while passing from the atmosphere tothe interior of the car may be tempered-J. e.,

cooled or heated, in order to avoid injury to the fruit being carried in either warm or cold weather.

Other objects and advanta es of the invention will be fully understood rom thefollow# ing description and claims when the same are read in connection with the drawings, ac-

companying and forming part of this specifi-` cation, in which:

Figure 1 is aside elevation of a car equipped with my improvements. larged vertical section of one ofthe inductors comprisedin the said improvements.\ Fig. 2 is a detail horizontal section of a portion of the car taken in a plane below the forarninous false floor'of thecar'body and above the conduits for leading atmospheric air to' the interior of the car. Fig. 3 is a transverse section showing the car body and my improvements with the upper portion of the body broken away. Fig. 4 is an enlarged longitudinal, vertical section of one of the tanks comprised in my improvements, and: Fig. 5 is a per# spective view of one of the induci `rs of the im .rovements, removed.

imilar letters designate corresponding parts in all of the views of the drawings, re-

erringto which:

A is the body of a car such as generally employed for the trans ortation of fruit and the like. The said bo y A is provided with 'suitable means for conducting air from the interior thereof to the atmosphere, with a View of preventing the collection of damp or Otherwise foul air in said interior, and in the present and preferred embodiment of my invention the said means. comprises two ventilators B B arran ed at opposite sides of the running board of t e car and adjacent to the transverse center thereof. The said ventilators B may be of any construction compatible with the pur ose of my invention, and for this reason I ave deemed it unnecessary to illustrate the same in detail.

C C are tanks suitably suspended below the bod A and arranged longitudinally adjacent to t e sides of the body as illustrated in Figs. 1 and 3, and D D are pipes contained in and extending lon itudinallyof the said tanks. There are re erably six of the pipes ,D iri each tank and each pipe is connected with an inductor arranged exterior of the body and a discharge mouth arrangedin the interior of the body. The tanks C and their complementary systems of pipes are l identical in construction, with the exception that one tank and one system of pi es are adapted for use at one side of the ody A and the other tank and system of pipesare adapted for use at the other side `of the body, Fig. 3,A

and for this reason a detailed description of the tank C and the system of pipes complementary thereto will suffice to impart a definite understanding of both tanks and the systems of pipes thereof. Referring therefore to Fig. 2, it will be seen that one of the pipes D is connected at one end to a pipe D which extends upward through the floor pro er a of the body A, and thence along sai loor ro er c and below the foraminous floorib of t e ody, and thence laterally'outward' through the side Wall c to the body and Vterminates outside the body in an inductor D2, and that 'the opposite end of the mentioned pipe D is connected to a ipe Da which reaches upward Ythrough the oor a of the body and then extends along said floor and terminates in a discharge mouth Dnwhich is perferably flared and is disposed horizontally as shown, and is located at any desired point in the area of the floor a. The next pi e D is connected at one end to a pipe E Wii similar to the pipe D and terminates in an inductor E2 similar to the inductor D2, and at its op osit'e end the mentioned ipe D is connecte to a pipe E3 which is simi ar to the i e 5 D3 andterminates in a dischar e mouth) E4 similar to but located at a di erent point from the discharge mouth E4. The pipe D next to the inner pipe is connected at one end Ato a pipe- F which is similar to the pipe D and terminates exterior. of the car in an inductor F2 similar to the 'inductor D2, and at its opposite end the mentioned pipe D is connecte vthrough the floor a of the body A and thence along the said Hoor a to or adjacent to one of' the corners of the bodyand then extends upward 4through the false floor b to a point a jacent to the top of the body and therel terminates in a flared dischargev mouth F4 which is preferably directed toward the center of the car as shown in Fig. 2, and is disposed or inclined slightly downward as shown in Fig. 3. The fourth pipe D fromA the outside of the series is connected at one end to a pi e G which extends u ward inductor D2, and the said pipe D is connected at itsv o posite end to a'pipe Ga which extends upwar through the oor a and then to a suitable point 1n the area of the body and is there rovided with a flared discharge ipe he third pipe D from the outsi e of the series is connected at one end to a pipe Hl which extends upward through the floor a of the body A and thencealng said floor and then laterally outwardv and terminates out- 40 side the car in an inductor H2 similar to the induc'tor G2, and the said third pipe D is connectedat its op osite end to a pipe H3 which extends upwar through the floor a and then to a suitable point in the area of the body and is there provided with la flared discharge mouth H4. The inner pipe D of the series is connected at one end to a ipe I which extends upward through the oor a of the body and thence along the said floor and then laterally outward and terminates outside the car in an inductor I2 similar to the inductor H2, and the said inner pipe D is connected'at its opposite end to a pipe I3 which extends up and through the floor a and then along the said floor to the corner at the'opposite end of the car but on the same side, w1th reference to the corner containing the pipe F3, and then extends upward through the false floor b to a oint adjacent to the top of the body and tiere terminates in a flared. discharge mouth I4 which is preferably directed-l toward the center of the car and slightly downward as illustrated.

As will be gathered from the foregoing the discharge mouths D4, E4, and F4 are arranged to the pipe F3 which extends upward along the said Hoor, and thence laterally outand terminates outside the car in an' inductor G2 similar to the before mentionedI adjacent to the op osite end of the body A with -reference t t eir res ective inductors D2, E2 and F2, and the disc arge mouths G4, H4 and I4 are arran ed at the opposite end of the body A with reerence to their respective inductors G2, H2 and I2. From this it follows that when the car is moving in the direction indicated by arrow, -air will ass with considerable force and in consi erable volume through the inductors, and then through the pipes D, and then through the several discharge pipes and the discharge mouths thereof into the interior of the car some 'of the air bein' discharged under the foraminous/floor b an some in the corners ofthe body and adjacent to the top thereof. By virtue of this 1t will be apparent that all portions of the interior of the car will be abundantly sup lied` with fresh air, with the result that all o the fruit carried in the car will be'preserved in a 85 wholesome state; also, that such air will sweep before it any damp or otherwise unwholesome air that may collect in the interior of the car and force the same out through the ventilators B. It will further be understood that the air rushing out through the ventilators Bl will create aV artial vacuum in the interior of the car, an that the air will tend to rush in through the vinductors to 0c'- cupy such partial vacuum, and consequently a current of fresh air will be continuously maintained through the car and the contents thereof.

As will be readil observed by comparison of Fi s. 1 and 2, th ably i'gher than wide,-and from this it fol-v lows that the inductors are adapted to receive a large volume of air andy yet do not offer any material lateral projection on the side of the car, and it will also be apparent that each inductor is provided as shown in Fig. 1a with a foraminous diaphla m c, designed to'exclude dust andv dirt, an that the pitch or sharp inclination of Ithe lower walls of the inductors will result in the prompt discharge of any dirt ordust that may bring up against the foraminous dia' hragms, and in that way lessen the liabi ity of the latter becoming choked.

The several inductorsi'are connected 115 through elbows d to. their respective pipes, and since the elbows'` are adapted to turn axially on the pipesfitfollows that the inductors may be swung vertically from the position shown to the reverse osition, so as to adapt them for'use when t 1e car is to be moved in the direction opposite to that indicated by arrow in Fi s. 1 and 2. In the position shown, the in uctors are supported Jy lateral pins e, and in their reversev position the said inductors are su ported by similar pins e. With a view of iolding the inductors against casual' movement from their working positions, l provide the keepers J, Figs. 1 and 3, which are pivotcd at f to the` 130 e inductors are consider- 10oiin body A and are arranged to be swung down and into engagement with the inductors in the manner shown in Fig., 1 and for the pureral circulation ofairthrough the b ody A, a

dry" and wholesome atmosphere is maintained in the body, and consequently the fruit is kept in a dry and wholesome state for an indefinite period, which is an important desideratum.

The tanks C may be Vprovided with any suitable means fortempering-i. e., cooling or yheating the air while the same is enroute through the pipes C, and from this it follows that in warm weather the air may be cooled precedent tothe supply of the same to the interior of the body A, and in cold weather the air may be heated before the same enters the interior of the body. As shown, each tank (lis provided with a removable foraminous bottom g, curved in conformity to and resting close against the series of pipes, a plurality of removable transverse partitions h, and a hingeddoor provided with a conventional or any other suitable fastener j for holding it in a closed position. As will be readily a preciated ice may be readily placed in the tan swhen the doors i thereof are open, and -it will also be a )preciated that such ice will cool the air whi e the same is enroute through the pi es D, and that the transverse partitions h will efiectually prevent the .ice threshing about and moving from end ae end in the tanks incident to the movements of the car and to the passage of the same up anddown grades. It will also be ap reci- .ated that the foraminous bottom g wil pro- ,tect the pipes D into the tanks.

against ice roughly thrown r When desirable pipes may be connected with the pipes D for -the purpose of supplying steam or any other heating agent to the said pi )es D, but these steam pipes I have decine it unnecessary to illustrate, since l io not confine myself to the eii'iployemnt of any specific means for either heating or cooling the air during the passage of the same to the interior of the car.

'lhi' adaptability of the bottoms g and the transverse partitions i to be removed from the tanks is ladvantageous inasmuch as it permits of' said bottom and partitions an( the pipes D being repaired wit i facility when occasion demands.

lith-a view of draining the pipes D of any water that may be deposited in the same by the air passing therethrough, the said pipes may be equipped. at convenient points with drain cocks, but these 1 have deemed it unnecessary to illustrate.

The construction herein illustrated and described constitutes the best embodiment of my-invention known to me, since it assures the maintenance of dry and pure air in the interior of the .car at all times, and this without detracting from the carrying capacity of the car or greatly increasing the cost of the same, but it is obvious that-in the future practice of' the invention such lchanges or modifications may be made as fairly fall within the scope of my invention'y as defined in the claims appended.

The arrangement of the foraminous floor l) above the several pipes intermediate the pipes D and the discharge mouths is advantageous since said foraminous floor is enabled to support the fruit loaded in the car and prevent the same from injuring the said pipes.

The maintenance of thoroughly dry air in the interior of the car will be appreciated as an important advantage when it-is consid` ei'ed that both the car and the -contents thereof are kept constantly dry, and hence when the car is unloaded or discharged of fruit it may be immediately reloaded with any commodity that it is desired to transport without the necessity of waiting for the car to dry out.
